Do we often encounter the problem of cardboard boxes becoming soft? Rainy summers inevitably have an impact on the humidity of the container. When weather is unavoidable, problems with soft paper can be solved through storage, production, and other aspects.
As is well known, raw paper and corrugated paper, among which corrugated paper has poor material and strong water absorption capacity; When paper is exposed to air for a long time, as the humidity in the air stabilizes, the cardboard begins to soften, which is normal. However, when ordering cardboard boxes, it is generally believed that softening refers to the softening of the pit paper, because pit paper is made by adding inner paper on the paper surface, resulting in poor material quality and strong water absorption capacity. We suggest customizing high weight, high-strength, and waterproof agent containing pit paper in areas with frequent rainfall to reduce some softening phenomena.
Paper box transportation is a necessary task, usually using convertible and box cars. Box cars are better able to maintain the humidity of cardboard than convertible cars, avoiding and reducing the softening of cardboard. Propose to use box type trucks for transportation, which is also a common type of truck used by major supply enterprises at present.
Of course, the storage time also depends on the material used for corrugated cardboard. If the fibers in the inner layer of the cardboard are short and the toughness is poor, it should be produced in a shorter time and entered into the next process as soon as possible, otherwise quality problems such as breakage and breakage may occur. Therefore, it is recommended not to have too much inventory. If there is a large inventory, it can be treated with moisture absorbing agents such as quicklime powder.
